希望一个简单的改变..我目前有一个下拉式导航菜单；我想更改为两层导航样式设置。类似于http://liptrot.org/journal/entries/two-tier-navigation-with-some-jquery/

当前的 HTML 和 jQuery：

<!DOCTYPE html>
<html>

<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
<meta name="viewport" content="width=device-width">

<script src="javascript/modernizr-2.6.2.min.js"></script>
<script type="text/javascript" src="javascript/jquery-1.9.1.min.js"></script>

<link type="text/css" href="css/main.css" rel="stylesheet">    

<!-- New JavaScript functions to enable dropdown navigation -->
<script type="text/javascript"> 
    $(document).ready(function(){        
        $('nav li ul').hide().removeClass('fallback');
        $('nav li').hover(
            function () {
                $('ul', this).stop().slideDown(300);
            },
            function () {
                $('ul', this).stop().slideUp(300);
            }
        );       
    });
</script>

<!-- New JavaScript functions to enable refresh of page content DIV -->
<script type="text/javascript"> 
    function getPageContent(a) {
            $.get(a, processContent, 'html').fail(function() { alert('There is a problem loading a resource. Please re-try');});
            $('#welcome').hide();
    }

    function processContent(file_data)
    {
        $("#PageContent").html(file_data);
    }
</script>


<style>
nav ul {
    text-align:left;    
}
nav ul li {
    float:left; 
    display:inline;
    border-right: 1px solid #083D72;
}
nav ul li:hover {
    background:#2D8FF0; 
}
nav ul li a {
    display:block; 
    color:#444; 
}
nav ul li ul {
    position:absolute; 
    width:180px;
    background:#09427C;
    font-size: 12px;    
}
nav ul li ul li {
    width:180px;    
}
nav ul li ul li a {
    display:block; 
    color:#444;
}
nav ul li ul li:hover a {}
nav ul li ul.fallback {
    display:none;
}
nav ul li:hover ul.fallback {
    display:block;
}

</style>
